Sr. Laser Design Engineer (Boston and Mountain View)

Sr. Laser Design Engineer

Lightmatter builds chips for artificial intelligence computing that leverage unique properties of light for efficient computing and communications. If you're a collaborative engineer or scientist who has a passion for innovation, solving challenging technical problems, and doing impactful work...work like building the world's first optical computers and developing high-speed silicon photonics-based optical interconnect solutions, consider joining the team at Lightmatter!

We are hiring a Senior Laser Designer . The selected candidate will partner with our Architecture Group and the internal engineering team to deliver groundbreaking products to the market. As a laser designer, you will design laser systems and provide detailed technical documents that describe our lasers. This will require a solid understanding of process technology, state-of-the-art laser design, laser modeling, silicon photonics platforms, and clear communication skills..

We are seeking a highly motivated and dedicated hands-on Laser Designer to help develop our next-generation lasers for our ground-breaking optical communication fabric alongside a team of world-class scientists and engineers. In this role, you will be defining the laser design, including the physical design  for a photonic-based communication fabric. From component-level design to top-level layout, you will be part of a team that enables high-bandwidth low-latency photonic interconnect/switch fabric.

In this  high impact  role, you will  work closely with our photonic, analog, and packaging teams to define and optimize the features needed to improve the power, performance, and area (PPA) of the next generation product. We are particularly looking for someone with hands-on expertise in semiconductor optical amplifier technology, laser cavity design, gain materials, lab testing and characterization  of lasers for volume production release. 

Join a tight-knit team where each individual’s contributions directly influence the success of the company and product. You'll have the opportunity to build a new kind of computer and photonic interconnect solutions from the ground up and to solve groundbreaking challenges along the way. Work with people who love to build and who thrive in technically diverse environments where great ideas are prioritized.
